Market context

On 16 June at 20:10 ET, the Detroit Tigers travel to Houston to face the Astros in a regular-season MLB fixture. The current 39% implied probability for a Tigers victory reflects a market-wide assessment that favours the home side, though the gap remains narrow enough to suggest meaningful uncertainty about pitching matchups and recent form.

Historical context matters here: the Astros have maintained a winning record against Detroit over the past three seasons, with Houston's roster stability and playoff experience typically translating to stronger performance in June matchups. However, the Tigers' 2024 campaign has seen notable improvements in their starting rotation, particularly following mid-season acquisitions. Comparable games between these franchises in similar timeframes—where Detroit entered as the underdog at 35–42% implied probability—have resolved roughly in line with pre-game expectations, suggesting the current market pricing reflects genuine competitive dynamics rather than systematic mispricing.

For programmatic traders, the key dependency is the confirmed starting pitcher announcement, typically released 24–48 hours before game time. A Tigers starter with a sub-3.50 ERA facing an Astros reliever-dependent bullpen could shift implied probabilities by 3–5 percentage points. Weather conditions at Minute Maid Park—particularly humidity affecting ball carry—warrant monitoring through meteorological feeds. Settlement occurs 2026-06-24, allowing sufficient time for postponement resolution under MLB's standard make-up protocols. Conditional order logic should account for the 50-50 tie resolution clause, though extra-inning ties remain statistically rare in modern baseball.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
